The ATSB is investigating the flight control systems event, involving Boeing 737-800, VH-YIJ, near Wellington, New Zealand, on 25 May 2017.
During approach, the crew detected a flap disagreement when the flap lever was selected from flap 25 to flap 40, and subsequently conducted a missed approach. During the missed approach, a flap overspeed occurred. The information was not relayed successfully to the cabin crew, resulting in the cabin crew incorrectly preparing a non-normal landing. Engineers could not reproduce the fault, however replaced the left-hand trailing edge flap position transmitter as a precaution.
As part of the investigation, the ATSB will interview the operating crew, obtain an engineering report and gather additional information.
A final safety report will be released following the conclusion of the ATSB’s investigation. Should a safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
